    Anonymous's first answer is correct. However, the second is wrong.

    8a-4+8-2a=156
    6a = 156 + 4 - 8
    6a = 152
    a = ?

    so then 6a = 25.33333333repeating? something or other?

  • Just think -

    1.whats the value for h in 12h+9=85?
    12h=76
    h=76/12
    h=6.333

    2.whats the value of m in 6m squared + 5 = 128?
    6m^2=123
    6m=square root of 123
    6m=11.091
    m=1.85

    3.what's the value of a in
    8a-4+8-2a=156
    combine terms so 6a+4=156
    6a=152
    a=25.333
